To modify communication mode
While using Multi-Drop communication mode in RS-422 or communication modes in RS-485,
several devices share only one BUS. When one device is using the BUS the other devices
cannot use the BUS at the same time. Therefore, for devices which are not using the BUS
should be set to Hi-Z at I/O. Auto-Toggling is a feature that sets this task automatically.
1. Communication modes are displayed in “Hardware Config” at “Settings” tab.
In RS-232 mode, no other communication modes are available.
